sdlDoes SDL3 reliably fire SDL_AudioDeviceEvent for USB headset connect/disconnect across platforms?
Goal Determine whether SDL3's SDL_AudioDeviceEvent reliably reports USB headset connect and disconnect across the major OS backends. Constraints SDL3 exposes SDL_EVENT_AUDIO_DEVICE_ADDED and SDL_EVENT_AUDIO_DEVICE_REMOVED, but each backend (PipeWire, PulseAudio, WASAPI, CoreAudio) implements the notification differently. Event ordering, duplicate delivery, a
SDL3 Event Handling: Renamed Enumerations Break Existing Switch Logic
Goal We need to validate that our event‑handling code continues to work after migrating from SDL2 to SDL3. The primary concern is the set of event type constants and struct layouts that have been reorganized in the SDL3 API, which can silently break switch statements that rely on SDL2 enumerations. Constraints & Uncertainty SDL3 introduces new event type
SDL_SetEventFilter compatibility when upgrading from SDL2 to SDL3
The goal is to confirm that an SDL_SetEventFilter callback installed in an SDL2 application continues to function unchanged when the same source is compiled against SDL3, ensuring that unwanted input events are still suppressed without adding notification noise. However, the SDL3 migration notes have not settled whether the function signature, the SDL_Event
